EMERY WI-IEEL DRESSER.

Specification of Letters Patent.

Patented Mar. 27, 1917.

Application filed November 8, 1912. Serial No. 730,191.

disks employed in constructing an emery' wheel dresser, and particularly the emery wheel dresser shown and described in the Letters Patent No. 990,193 granted to me on April 18, 1911, in which device screw threaded washers are employed which are secured upon a central bushing to hold the disks in p ace.

These washers sometimes become loosened as the dressing tool is rotated at a high rate of speed and the several disks become loosened and loosen their engagement with each other, thus injuring the efficiency of the tool.

In this device means for securely interlocking the washers with the terminal disks and with the central bushing are provided so that all danger of this kind is eliminated. The invention comprises the combination and arrangement of partsand construction of details as hereinafter described, shown in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a face view of the improved form of dressing tool; Fig. 2 is a separate view of one of the washers and Fig. 3 is a transverse section of the tool showing the turned over extremities of the central sleeve. Fig. 4 is an isometric view of one of the disks employed in constructing the emery wheel dresser, showing lugs which interlock or encess in each face thereof, projecting lugs on the faces of each of said disks adapted to en gage with the next adjacent disk.

In these views 1 and 4 arethe disks which interlock with each other so as to rotate in and a lug 12 on the opposite face. One of V disks 4 has a lug 11 and one a lug 12. The disks I have, moreover, recessescomplemental to the lugs 11 and 12 whereby disks 1 interlock and one of disks 4 has a recess comple nental to lug 12 on the adjacent disks 1, while the other disks 4 have a recess complemental to the lug 11 on the adjacent disks 1.

The washers 3, 3 and terminal disks 4,4 are peculiarly constructed to interlock so as to rotate together and the washersare also 'provided with means for interlocking with the central sleeve so that rotation of any part upon the sleeve will be impossible.

To accomplish these results the washers areprovided with the recesses or'slots 6 upon their. outer edges, and also with the slots or notches 7 7 upon their inner edges.

The outer disks are also provided with corresponding lugs 8, 8 with which the'slots 6, 6 are engaged, and for convenience the slots in each part are oppositely placed so as to be quickly put in place. These lugs will 7 then prevent the washers from turning upo the disks.

The central sleeve 2 is made slightly longer than the tool composed of disks and washers and the projecting ends are turned back over the washers at 9, 9 thus inclosing the parts of the tool between them. The exterior of the turned over portion is flattened to bear closely upon the handle H.

The portions of the turned over edges 8, 8 opposite the openings 7, 7 in the washers are then forced into these openings at 10 by means of a suitable tool and the application of power, the effect being to prevent the central disks or washers from turning upon the bushing, and the parts will all then be securely locked together and the disks can not escape from rigid confinement.

Having described the invention what I claim as new and desire-to secure by Letters Patent is:

1. The combination in an emery wheel gage a recess in the adjacent disk on each side thereof and prevent the independent ro- .tation of the disks with respect to each other,

an end disk disposed at each end of said series and each having the face adjacent the said series complemental to and in engage ment with the face of the disk adjacent thereto and the other face having projecting lugs thereon, a sleeve upon which said series of disks and the end disks are disposed, said sleeve having projections at each end thereof integral therewith, end washers disposed on the said sleeve, one adjacent each of said end disks and having recesses therein adapted to engage the projecting lugs on said end disks and also having recesses therein adapted to engage the projections on said sleeve whereby all of said disks, end washers and the sleeve are secured against independent rotation with respect to each other, and a handle upon which said sleeve is rotatably journaled.

2. The combination in an emery wheel dresser, of a series of disks each having a recess in each face thereof, a projection on each face of each of said disks adapted to engage a recess on the adjacent disks and prevent the independent rotation of the disks with respect to each other, an end disk disposed at each end of said series and having the face adjacent the said series complemental to and in engagement with the adjacent disk of the series and the other face having projecting lugs thereon, a sleeve upon which said series of disks and the end disks are disposed and having projections integral therewith, end washers disposed on the said sleeve one of which is adjacent each of said end disks and having recesses therein adapted to engage the projecting lugs on said end disks and also having recesses therein adapted to engage the projections integral with said sleeve, whereby all of the said disks and washers and the sleeve are secured against rotation with respect to each other, and the ends of said sleeve being turned over said end washers, whereby said end washers, end

disks and series of disks are secured against 7 longitudinal movement with respect to said sleeve, and a handle upon which said sleeve is rotatably journaled.

In testimony whereof, I hereunto set my hand this 26 day of September 1912.
